The development of sensors and printed electronics has brought about a significant advancement in the field of technology. The SonicMEMs lab at Cornell University has recently published an article titled "Laser-Induced Graphene Sensors Printed with Conductive and Dielectric Inks", and it showcases a major breakthrough in this field by demonstrating the design and implementation of a laser-induced graphene (LIG) Kapton circular diaphragm gauge pressure sensor with a multi-resistor network.

This white paper represents the first-ever combination of LIG sensors with printed electronics (PE) to create a fully functional microsystem. The study showcases how the BotFactory SV2 PCB printer is utilized to print the wiring and encapsulation of the LIG sensor with conductive and dielectric inks (CI and DI). This breakthrough offers a number of advantages for the LIG sensors, including off-grid power, read-out circuitry, amplification, and simple wireless data transmission.

One of the most significant achievements of this study is the development of a circular diaphragm gauge pressure sensor that can measure pressure in a variety of environments. The sensor is designed to be both reliable and efficient, making it ideal for use in a variety of industries, including healthcare, aerospace, and automotive. The use of LIG sensors with printed electronics opens up a new world of possibilities for these industries, as they can now incorporate sensors into their products without the need for bulky and expensive electronics.

Another important highlight of this paper is the use of the automated solder paste dispensing and pick-and-place of electronic facility offered by the SV2 printer. This features allows for the creation of complete microsystems, including the integration of microcontrollers, thin-film batteries, passive components, and antennas, among others. These microsystems can then be utilized in a variety of applications, such as medical devices, environmental sensors, and more.

The development of LIG sensors printed with conductive and dielectric inks marks a significant step forward for the field of technology. The use of these sensors has the potential to revolutionize a number of industries, and the combination with printed electronics creates even more opportunities for innovation. This white paper serves as a valuable resource for those in the field of technology, as it highlights the potential applications of LIG sensors and printed electronics and showcases the latest advancements in this exciting field.
